 to give, at a distance, the effect of full bloom ; but the 

 common aspen leaf is not thus blanketed in infancy. 



The Lombardy poplar is the most columnar — fastigi- 

 ate, as botanists call it — of all our trees. Several small 

 ones are near the ' ' Pond, ' ' but a fine cluster of full-grown 

 ones may be seen at the extreme northern end of the

Balsam poplar and balm of Gilead are two less familiar 

 members of the family ; and it is interesting to note, in 

 this as in similar instances, the resemblances that be-

 most to defy description. Indeed, the comparison and 

 contrast of allied forms is one of the most important 

 sources of pleasure in plant study, and increases our

Just as this earth is the theatre of man's evolution and
